Microsoft announced today at CTIA that it will be increasing its investments in digital rights management technology or DRM, which ensures digital content is being used properly. No word on how big the investment will be.

"We're looking at protecting new forms of digital media on handsets, like games or ringtones. There are also device-to-device scenarios we're looking into, so we can help enhance both the security and portability of content," according to Adam Anderson, Product Manager for Windows Digital Media.
